Trait eclectic::set::Remove [−] [src]

pub trait Remove<Q: ?Sized = Self::Item>: Get<Q> + Remove {
    fn take(&mut self, item: &Q) -> Option<Self::Item>;

    fn remove(&mut self, item: &Q) -> bool { ... }
}

A set that supports removal using items of type &Q.

Required Methods

fn take(&mut self, item: &Q) -> Option<Self::Item>

Removes and returns the item in the set that is equivalent to the given item.

Returns None if the set contained no such item.

Provided Methods

fn remove(&mut self, item: &Q) -> bool
